Though it's hard to tell from the GIF, it looks like Cingrani is throwing a slider that breaks like a curveball. In other words, as others have posted, a slurve.
A slider is thrown with a flick of the wrist, creating vertical spin. A curve is thrown by pushing your thumb from the bottom of the ball to the top, creating horizontal spin. In the GIF, it looks more like he's flicking his wrist. But it's hard to tell.
We cannot solve our problems with the same thinking we used when we created them. - Albert Einstein
